In jashubbard/edfR: Basic functions for importing SR-Research Eyelink EDF files

Create a fixation scatterplot from EDF

Description

This creates a scatterplot of fixations read from an EDF file.

Usage

edf.plot(EDFfile = NULL, fixdata = NULL, outfile = NULL, outlier.rm = F,
  res = NULL, flip = T, theme = "black", crosshairs = T,
  plot.title = "")

Arguments

EDFfile	path to an EDF file. If you have already-loaded data, leave this as NULL
fixdata	optionally you can provide a data frame of already imported fixation data from edf.events. It expects the fields gavx and gavy
outfile	if provided, it will save the plot as a PDF with this file name
outlier.rm	logical specifying whether to remove outlier fixations (>3SDs from mean)
res	array specifying resolution of monitor. Only this region will be plotted.
flip	logical indicating whether to flip the y axis so origin is in upper-left (defualt=TRUE).
theme	either "black" or "white" specifying the plot theme (yellow on black or black on white)
crosshairs	logical whether to plot crosshairs over the median x and y coordinates (dotted red lines)
plot.title	title to put at the top of the plot
